El modelo energético mundial se basa en combustibles fósiles, el cual ha venido siendo sustituido por consideraciones ambientales y económicas, dándole paso a la biomasa y a las plantaciones dendroenegéticas. En Chile, las energías renovables no convencionales (ERNC) vienen ganando espacio, además la nación ha abocado esfuerzos en especies que posean buen potencial energético. Así, este estudio tiene como objetivo evaluar el potencial físico-químico, energético y perfiles térmicos de dos especies (Paulownia elongata x fortunei y Miscanthus x giganteus) para el uso energético en tres sitios contrastantes de Chile. Los análisis fueron realizados en su mayoría bajo los estándares de las Normas DIN. Los resultados para Paulownia mostraron diferencias entre los sitios, obteniendo los mejores resultados en el sitio El Vergel con un porcentaje de lignina de 34,84%, cenizas de 1,16%, material volátil de 81,70%, carbono de 47,02% y una densidad energética líquida (DEL) de 2,16 GJ m-3. Para Miscanthus los mejores resultados también fueron registrados en El Vergel, con porcentaje de lignina de 30,60%, cenizas de 2,84%, material volátil de 82,26% y carbono de 45,97% y una DEL de 1,67 GJ m-3, destacando que los mejores resultados de El Vergel son para la densidad D1. Respecto al perfil térmico (TGA-DTG), la Paulownia presentó pérdida de masa mayor que el Miscanthus y tuvo ignición a menor temperatura de 197,76 °C y 209,66 °C respectivamente. Por lo tanto, el mayor porcentaje de residuo lo presentó el Miscanthus con 5,63%. Consiguientemente, ambas especies presentan características deseables para su uso energético.

Set Up

Cultivation of Miscanthus x giganteus L. (Mis) with annual harvest of biomass could provide an additional C source for farmers. To test the potential of Mis-C for immobilizing inorganic N from slurry or manure and as a C source for soil organic matter build-up in comparison to wheat (Triticum aestivum L.) straw (WS), a greenhouse experiment was performed. Pot experiments with ryegrass (Lolium perenne L.) were set up to investigate the N dynamics of two organic fertilisers based on Mis at Campus Klein-Altendorf, Germany. The two fertilisers, a mixture of cattle slurry and Mis as well as cattle manure from Mis-bedding material resulted in a slightly higher N immobilisation. Especially at the 1st and 2nd harvest, they were partly significantly different compared with the WS treatments. The fertilisers based on Mis resulted in a slightly higher microbial biomass C and microbial biomass N and thus can be identified as an additional C source to prevent nitrogen losses and for the build-up of soil organic matter (SOM) in the long-term.

Ghg Fluxes

Miscanthus x giganteus (miscanthus), a perennial biomass crop, allocates more carbon belowground and typically has lower soil greenhouse gas (GHG) emissions than conventional feedstock crops, but best practices for nutrient management that maximize yield while minimizing soil GHG emissions are still debated. This study evaluated the effects of four different fertilization treatments (digestate from a biodigester, synthetic fertilizer (urea), hydrochar from the hydrothermal carbonization of digestate, and a control) on soil GHG emissions and biomass yield of an established miscanthus stand grown on abandoned agricultural land. Soil GHG fluxes (including CH4, CO2, and N2O) were sampled in all treatments using the static chamber methodology. Average biomass yield varied from 20.2 Mg ha−1 to 23.5 Mg ha−1, but there were no significant differences among the four treatments (p > 0.05). The hydrochar treatment reduced mean CO2 emissions by 34% compared to the control treatment, but this difference was only statistically significant in one of the two sites tested. Applying digestate to miscanthus resulted in a CH4 efflux from the soil in one of two sites, while soils treated with urea and hydrochar acted as CH4 sinks in both sites. Overall, fertilization did not significantly improve biomass yield, but hydrochar as a soil amendment has potential for reducing soil GHG fluxes.

Paulownia Elongata

The density, shrinkage and swelling of Paulownia elongata and P. fortuneii wood were researched. The study material was provided by Boda Vukovojac, B. Sc., who established the Paulownia plantation and sample plots on the territory of the Municipality Bela Crkva. The study results show the differences between the analyzed properties of these two species. The study results were also compared with the results of the similar species of wood. The data shows that the study wood can be used in wood products that are not subject to great loads during exploitation. Further study should investigate the liability of these wood species to form tension wood and deformations in the conditions of variable hygroscopic moisture.
